German federal prosecutors have arrested a Ukrainian national in the state of Brandenburg on suspicion of espionage for Russia, the Federal Public Prosecutor's Office in Karlsruhe announced on Thursday. The suspect, identified only as Vadym Y., is accused of using contacts within the European defence industry to obtain sensitive military information.
According to the Federal Prosecutor General's Office, Vadym Y. had been in contact with a Russian intelligence service through an intermediary since at least July 2025. In the context of Russia's war against Ukraine, he is said to have gathered militarily relevant data from within Germany, including details on the production of armoured vehicles, ammunition, and explosives, as well as information about personnel and military installations at sites used to secure NATO's eastern flank.
Espionage methods and investigation
While some of the information was publicly accessible, the suspect is alleged to have deliberately obtained other details by approaching individuals working in the European defence industry. The Federal Public Prosecutor's Office is handling the case because it affects Germany's national security and involves suspected espionage on behalf of a foreign power.
The arrest comes at a time when German security authorities are issuing increasingly stark warnings about suspected Russian espionage and sabotage activities. In April 2026, a man was arrested in Berlin on suspicion of passing information about Germany's military support for Ukraine, defence companies, and military convoys to a Russian intelligence service. That case also involved potential targets for sabotage operations.
Another case involves a 53-year-old Ukrainian from Attendorn in North Rhine-Westphalia. According to a ruling by the Federal Court of Justice made public in October, he is accused of monitoring another Ukrainian in a refugee shelter on behalf of Russia's domestic intelligence service, the FSB, and of passing on information about that person's contacts via Telegram. Charges have now been brought against him for acting as an intelligence agent.
These cases differ in their specific allegations, but they illustrate that German authorities are investigating both the gathering of military information and the surveillance of individuals who might be of interest to Russia. The latest arrest in Brandenburg underscores the breadth of suspected Russian intelligence activities on German soil.
The investigation is ongoing, and the precise background to the alleged information gathering, as well as any possible accomplices, remains to be established. Until a final conviction is reached, the presumption of innocence applies to the accused.
This development comes amid broader concerns about Russian espionage across Europe. Recent reports have highlighted growing Russian migration to the EU and increased activity in the Arctic, where the EU has shifted its strategy to focus on security. The arrest also follows criticism from a former US general that the Trump administration is siding with Russia against Ukraine, adding to the geopolitical tensions surrounding the conflict.
